I am an associate professor in the School of Computational Science and Engineering (CSE) at Georgia Tech. My research is in the area of high-performance computing.

This year, I am also serving as both the Associate Chair of Academic Affairs in the School of CSE and as the Director of CSE Programs.

Research: The HPC Garage [@hpcgarage].
My lab is developing automated tools and techniques to tune, to analyze, and to debug software for parallel machines, including emerging high-end multi/manycore architectures and accelerators. We focus on applying these methods to CSE applications, which include computer-based simulation of natural and engineered systems and data analysis.

I received my Ph.D. in Computer Science from the University of California, Berkeley, in January 2004, in the BeBOP group, under Profs. James Demmel and Katherine Yelick. I was a post-doctoral researcher in the Center for Applied Scientific Computing at the Lawrence Livermore National Laboratory, where I worked with Dr. Dan Quinlan on the ROSE project.

Though my last name looks vaguely Slavic, I'm actually a Vietnamese-American. It's a long story.

I am a great admirer of human ingenuity, as exemplified by The Watts Towers in Los Angeles; Peeps Shows I II, III, and IV; Projekt P.I.W.O.; verse for geeks; and its seemingly inherent desire to bridge the gap between theory and practice; among others.
